Der Erfindung liegt die Aufgabe zugrunde, ein kompaktes Saugreinigungsgerät mit den eingangs beschriebenen Merkmalen anzugeben, welches bei einem kompakten Aufbau auf unterschiedlichen Bodenbelägen ein gutes Reinigungsvermögen aufweist.Of the Invention is based on the object, a compact Saugreinigungsgerät with the Specify features described in the introduction, which in a compact Structure on different floor coverings has a good cleaning power.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Akkumulatoreneinheit auf einem Lithium-Ionen-System basiert und bezogen auf ihre Gesamtvolumen eine Energiedichte von mehr als 200 Wattstunde pro Liter (Wh/l) aufweist. Während bei den Saugrobotern ausgehend von einem vorgegebenen, geringen Bauvolumen und der Bereitstellung von Nickelmetallhydrid-Akkumulatoren als Stromquelle bei der Auslegung stets eine geringe elektrische Leistung aller Komponenten angestrebt wurde, liegt der vorliegenden Erfindung die Erkenntnis zugrunde, dass durch die Verwendung eines Lithium-Ionen-Systems mit einer Energiedichte von mehr als 200 Wh/l, vorzugsweise mehr als 250 Wh/l, als Akkumulatoreneinheit eine von den bekannten Ausführungen abweichende Auslegung der elektrischen Komponenten und dadurch eine Verbesserung der Saugeigenschaften unter Beibehaltung einer kompakten Bauweise der Vorrichtung ermöglicht wird.The The object is achieved in that the accumulator unit is based on a lithium-ion system and based on their total volume, an energy density of more than 200 Watt hour per liter (Wh / l). While with the vacuum robots starting from a given, low volume and the provision Nickel metal hydride batteries as a power source in the design always a low electrical output of all components was sought, The present invention is based on the finding that by the use of a lithium-ion system with an energy density of more than 200 Wh / l, preferably more than 250 Wh / l, as the accumulator unit one of the known designs Deviating interpretation of the electrical components and thereby a Improving the suction properties while maintaining a compact Construction of the device allows becomes.
Die Akkumulatoreneinheit kann im Rahmen der Erfindung aus zumindest einem Lithium-Ionen-Akkumulator, einem Lithium-Polymer-Akkumulator, einem Lithium-Mangandioxid-Akkumulator oder einem Lithium/Lithiumkobaltoxid-Akkumulator gebildet sein. Der Zellenaufbau der Lithium-Polymer-Akkumulatoren erlaubt die Fertigung von dünnen Folienbatterien, weshalb Lithium-Polymer-Akkus in fast beliebigen und insbesondere auch ungleichmäßigen Formen gefertigt werden können. Lithium-Polymer-Akkumulatoren können unter optimaler Raumnutzung unregelmäßige Zwischenräume ausfüllen. Lithium-Mangandioxid-Akkumulatoren zeichnen sich durch eine besonders hohe Betriebssicherheit aus, so dass spezielle Schutzschaltungen nicht zwingend erforderlich sind. Des Weiteren können Lithium-Mangandioxid-Akkumulatoren kostengünstig gefertigt werden und enthalten keine Schwermetalle, so dass sie bei der Entsorgung und bei einem Defekt vergleichsweise problemlos gehandhabt werden können.The Accumulator unit can in the context of the invention of at least a lithium ion secondary battery, a lithium polymer secondary battery, a lithium manganese dioxide rechargeable battery or a lithium / lithium cobalt oxide rechargeable battery be formed. The cell structure of the lithium polymer accumulators allows the production of thin Foil batteries, which is why lithium-polymer batteries in almost any and in particular also uneven shapes can be made. Lithium polymer accumulators can fill in irregular spaces under optimal use of space. Lithium manganese dioxide batteries are characterized by a particularly high level of operational safety, so that special protection circuits are not mandatory. Furthermore you can Lithium manganese dioxide accumulators are manufactured inexpensively and do not contain heavy metals, so they are at disposal and can be handled comparatively easily with a defect.
Im Rahmen einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Akkumulatoreneinheit einen Akkumulator mit einer Elektrode aufweist, deren Oberfläche mit einer Nanostruktur versehen ist, wobei die Oberfläche in Bezug auf eine glatte Oberfläche zumindest um einen Faktor 5, vorzugsweise zumindest um einen Faktor 10 vergrößert ist. Der maximale Lade- und Entladestrom ist im Wesentlichen durch die Oberfläche der Elektrode bestimmt. Durch die Oberflächenvergrößerung aufgrund einer Nanostrukturierung können dabei auch bei einem Akkumulator mit einer großen Kapazität und einer entsprechend großen Menge an elektrochemisch aktivem Material sehr große Lade- und Entladeströme erreicht werden. In Bezug auf ein Saugreinigungsgerät kann beispielsweise in einem sehr kurzen Zeitintervall von typischerweise weniger als 10 Minuten, vorzugsweise weniger als 5 Minuten eine Schnellaufladung erfolgen. Des Weiteren kann auch in besonders vorteilhafter Weise, beispielsweise zur Reinigung eines stark verschmutzten Bodenabschnittes, kurzzeitig ein erhöhter Entladestrom bereitgestellt werden. Im Rahmen der beschriebenen Ausgestaltung des Akkumulators mit einer nanostrukturierten Elektrode kann dieser beispielsweise als Lithium-Nanophosphat-Akkumulator ausgeführt sein.Within the scope of a preferred embodiment of the invention, it is provided that the accumulator unit has an accumulator with an electrode whose surface is provided with a nanostructure, wherein the surface increases at least a factor of 5, preferably at least a factor of 10, with respect to a smooth surface is. The maximum charge and discharge current is essentially determined by the surface of the electrode. Due to the surface enlargement due to a nanostructuring can also be in an accumulator with a large capacity and a correspondingly large amount of electrochemically active material very large charge and discharge currents can be achieved. With respect to a vacuum cleaner, for example, rapid charging may occur in a very short time interval of typically less than 10 minutes, preferably less than 5 minutes. Furthermore, in a particularly advantageous manner, for example for cleaning a heavily soiled floor section, an increased discharge current can be provided for a short time. In the context of the described embodiment of the accumulator with a nanostructured electrode, this can be embodied, for example, as a lithium-nano-phosphate accumulator.
Der zumindest eine Akkumulator der Akkumulatoreneinheit ist entweder verdeckt in einem Aufnahmeraum innerhalb des Gehäuses des Saugreinigungsgerätes angeordnet oder derart in einem offenen Aufnahmeraum des Gehäuses eingesetzt, dass der Akkumulator einen Teil der Außenfläche des Gehäuses bildet, wobei vorzugsweise die Kontur des Gehäuses etwa flächenbündig in die angrenzende Außenkontur des Akkumulators angrenzt.Of the at least one accumulator of the accumulator unit is either concealed arranged in a receiving space within the housing of Saugreinigungsgerätes or inserted in such an open receiving space of the housing, that the accumulator forms part of the outer surface of the housing, wherein preferably the contour of the housing approximately flush in the adjacent outer contour of the accumulator adjoins.
Vorzugsweise weist die Akkumulatoreneinheit mindestens einen Akkumulator auf der zum Zwecke einer optimalen Raumausnutzung des innerhalb des Gehäuses vorhandenen Einbauraumes die dickwandige und dünnewandige Abschnitte und/oder eine von Stabbatterien abweichende Außenkontur aufweist. Die Außenkontur ist an die Form des im Gehäuse vorhandenen Einbauraumes angepasst. Ferner wird der Aufnahmeraum für den Akkumulator und die äußere Geometrie des Akkumulators passgenau aufeinander abgestimmt. Im Gegensatz zu üblichen, stabförmigen Akkumulatoren wird durch die beschriebene Ausgestaltung eine Anordnung der Akkumulatoren in ansonsten ungenutzten Zwischenräumen ermöglicht, wodurch die Volumennutzung verbessert und die Außenabmessungen des Saugreinigungsgerätes verringert werden können. Des Weiteren ist bei tragbaren Geräten aus dem Bereich der Unterhaltungselektronik, die mit Lithium-Ionen-Akkumulatoren ausgerüstet sind, bekannt, dass durch den Einsatz eines nicht genau auf die Ladeelektronik abgestimmten Ersatzakkumulators eine Zerstörung des Akkumulators und des Gerätes selbst auftreten kann. In Extremfällen kann der Akkumulator explodieren oder entflammen. Bei Saugreinigungsgeräten für die autarke Reinigung, die üblicherweise unbeaufsichtigt sind, muss ein solches Fehlverhalten ausgeschlossen werden. Durch eine unregelmäßige, nicht standardisierte Formgebung des Aufnahme raumes und der Akkumulatoreinheit kann die Verwendung nicht autorisierter Ersatzakkus weitgehend ausgeschlossen werden.Preferably the accumulator unit has at least one accumulator for the purpose of optimal use of space within the housing existing installation space the thick-walled and thin-walled sections and / or a Having rod shells deviating outer contour. The outer contour is due to the shape of the case adapted to existing installation space. Furthermore, the recording room for the Accumulator and the outer geometry of the accumulator accurately matched. In contrast to usual, rod-shaped accumulators the arrangement described describes an arrangement of the accumulators in otherwise unused spaces, allowing volume usage improved and the outside dimensions of the vacuum cleaning device can be reduced. Furthermore, with portable devices in the field of consumer electronics, which are equipped with lithium-ion batteries, known that by the use of a not exactly matched to the charging electronics Spare accumulator a destruction of the accumulator and the device yourself can occur. In extreme cases, the accumulator can explode or inflame. In vacuum cleaning devices for self-cleaning, usually unattended, such misconduct must be excluded become. By an irregular, not standardized shape of the recording space and the accumulator unit The use of unauthorized replacement batteries can be largely excluded become.
Im Rahmen einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die Akkumulatoreneinheit zumindest zwei unterschiedlich geformte Akkumulatoren aufweist, die separat voneinander an voneinander beabstandeten Stellen des Saugreinigungsgerätes angeordnet sind. Durch die Verteilung der Akkumulatoreneinheit auf unterschiedliche Gehäuseabschnitte können Räume zwischen den einzelnen Komponenten des Saugreinigungsgerätes ausgefüllt werden. Durch die verteilte Anordnung der Akkumulatoreneinheit auf zumindest zwei Akkumulatoren ist ferner eine optimale Gewichtsverteilung erreichbar.in the A preferred embodiment of the invention is provided, that the accumulator unit at least two differently shaped accumulators having, separately from each other at spaced locations of the vacuum cleaning device are arranged. By the distribution of the accumulator unit on different housing sections can Spaces between the individual components of Saugreinigungsgerätes be filled. Through the distributed Arrangement of the accumulator unit on at least two accumulators Furthermore, an optimal weight distribution can be achieved.
Aufgrund der erfindungsgemäß hohen Energiedichte von mehr als 200 Wh/l und vorzugsweise mehr als 250 Wh/l kann die Akkumulatoreneinheit auch bei einer hohen Energiekapazität von typischerweise mehr als 100 Wattstunde (Wh), bevorzugt mehr als 150 Wh, derart kompakt ausgeführt werden, dass das Gesamtvolumen weniger als 5 % des Gesamtvolumen des Saugreinigungsgerätes beträgt. Das Volumen des gesamten Saugreinigungsgerätes ist typischerweise kleiner als 25 Liter, vorzugsweise kleiner als 20 Liter, wobei die Gerätehöhe vorzugsweise kleiner als 180 mm, besonders bevorzugt kleiner als 150 mm ist und wobei die Grundfläche des Saugreinigungsgerätes vorzugsweise weniger als 1.500 cm2 beträgt.Due to the inventively high energy density of more than 200 Wh / l and preferably more than 250 Wh / l, the accumulator unit can be made so compact even at a high energy capacity of typically more than 100 watt hour (Wh), preferably more than 150 Wh the total volume is less than 5% of the total volume of the Saugreinigungsgerätes. The volume of the entire vacuum cleaning device is typically less than 25 liters, preferably less than 20 liters, wherein the device height is preferably less than 180 mm, more preferably less than 150 mm and wherein the base of the Saugreinigungsgerätes preferably less than 1500 cm 2 .
